The shutdown command administratively disables the entity. When disabled, an entity does not change, reset, or remove any configuration settings or statistics. Many entities must be explicitly enabled using the
no shutdown command. The operational state of the entity is disabled as well as the operational state of any entities contained within. Many objects must be shut down before they may be deleted.
The no form of the command puts an entity into the administratively enabled state.

This command enables CPM hardware queuing per peer. This means that when a peering session is established, the router will automatically allocate a separate
CPM hardware queue for that peer.
The no form of the command disables

When a source address is specified for the ptp application, the port-based 1588 hardware timestamping assist function will be applied to PTP packets matching the IPv4 address of the router interface used to ingress the SR/ESS or IP address specified in this command. If the IP address is removed, then the port-based 1588 hardware timestamping assist function will only be applied to PTP packets matching the IPv4 address of the router interface.

When tacplus-map-to-priv-lvl is enabled, and tacplus authorization is enabled with the
use-priv-lvl option, typing
enable-admin starts an interactive authentication exchange from the SR OS node to the TACACS+ server. The start message (service=enable) contains the userid and the requested admin-priv-lvl. Successful authentication results in the use of a new profile (as configured under config>system>security>tacplus>priv-lvl-map).
This command creates a new ca-profile or enter the configuration context of an existing
ca-profile. Up to 128 ca-profiles could be created in the system. A
shutdown the ca-profile will not affect the current up and running
ipsec-tunnel or
ipsec-gw that associated with the
ca-profile. But authentication afterwards will fail with a
shutdown ca-profile.
Executing a no shutdown command in this context will cause system to reload the configured cert-file and crl-file.
A ca-profile can be applied under the

member user-profile-name [user-profile-name…]
The no form of this command deletes access user access to a profile.
[no
] new-password-at-login
The no form of the command does not force the user to change passwords.
The use of the hash keyword sets the initial password when the user is created or modifies the password of an existing user and specifies that the given password was hashed using hashing algorithm version 1.
The use of the hash2 keyword specifies that the given password is already hashed using hashing algorithm version 2. A semantic check is performed on the given password field to verify if it is a valid hash 2 key to store in the database.
In previous releases, the password command syntax included the hash (hash version 1) parameter that allowed you to specify a password and encryption. For example,
config>system>security>user# password testuser1
config>system>security# user testuser1
config>system>security>user$ password xyzabcd1
config>system>security>user# exit
config>system>security# info
-------------------------------------
...
user "testuser1"
password "I/VhQSk/FWY" hash
exit
...
-------------------------------------
config>system>security#
In the current release, the password command allows you also to specify a different hashing scheme, hash version 2.
config>system>security# user testuser1
config>system>security>user$ password "zx/Uhcn6ReMOZ3BVrWcvk." hash2
config>system>security>user# exit
config>system>security# info
-------------------------------------
...
user "testuser1"
password "zx/Uhcn6ReMOZ3BVrWcvk." hash2
exit
...
-------------------------------------
config>system>security#
For example: config>system>security>user# password “south#bay?”
To insert a # or
? characters, they must be entered inside a notepad or clipboard program and then cut and pasted into the Telnet session in the password field that is encased in the double quotes as delimiters for the password.
If a password is entered without any parameters, a password length of zero is implied: (carriage return).
The no form of the command allows the user access to navigate to directories above their home directory.
[no
] rsa-key

If a new user-name is entered, the user is created. When an existing
user-name is specified, the user parameters can be edited.
When creating a new user and then entering the info command, the system displays a password in the output. This is expected behavior in the hash2 scenario. However, when using that user name, there will be no password required. The user can login to the system and then <ENTER> at the password prompt, the user will be logged in.

This configuration instructs SR OS to send no username nor password in the TACACS+ start message, and to display the server_msg in the GETUSER and GETPASS response from the TACACS+ server. Interactive authentication can be used to support a One Time Password scheme (e.g. S/Key). An example flow (e.g. with a telnet connection) is as follows:
|
•
|
SR OS displays the server_msg (which may contain, for example, an S/Key for One Time Password operation), and collects the password.

A source is defined as a unique combination of SAP and MAC source address (mac-monitoring) or SAP and source IP address (ip-src-monitoring).

When a policer is declared as in an “exceed” state, it will remain as exceeding until a contiguous conformant period of detection-time passes. The
detection-time only starts after the exceed-action hold-down is complete. If the policer detects another exceed during the detection count down then a hold-down is once again triggered before the policer re-enters the detection time (that is, the countdown timer starts again at the configured value). During the hold-down (and the detection-time), the policer is considered as in an “exceed” state.
The hold-down is cleared after approximately the configured time in seconds after it was set. The
hold-down seconds option should be selected for protocols that receive more than one packet in a complete handshake/negotiation (for example, DHCP, PPP).
hold-down is not applicable to a local monitoring policer. The “detection-time” will only start after any
hold-down is complete. During the
hold-down (and the detection-time), the policer is considered as in an “exceed” state. The policer may re-enter the hold-down state if an exceed packet is detected during the detection-time countdown. The allowed values are [none|1..10080|indefinite].
This command configures a monitoring policier that is used to monitor the aggregate rate of several protocols arriving on an object (for example, SAP). When the local-monitoring-policer is determined to be in a non-conformant state (at the end of a minimum monitoring time of 60 seconds) then the system will attempt to allocate dynamic policiers for the particular object for any protocols associated with the local monitor (for example, via the “protocol xyz enforcement” CLI command).
Once this policer-name is referenced by a protocol then this policer will be instantiated for each “object” that is created and references this DDoS policy. If there is no policer free then the object will be blocked from being created.
The hold-down is cleared after approximately the configured time in seconds after it was set. The
hold-down seconds option should be selected for protocols that receive more than one packet in a complete handshake/negotiation (for example, DHCP, PPP).
